Alleviation of Liver Dysfunction, Oxidative Stress and Inflammation Underlies the Protective Effect of Ferulic Acid in Methotrexate-Induced Hepatotoxicity.

INTRODUCTION

In multiple studies, involvement of oxidative stress in the pathogenesis of methotrexate (MTX)-mediated liver damage has been confirmed. Use of many drugs has been examined experimentally in order to prevent or diminish oxidative stress. However, no study has yet examined the effects of ferulic acid (FA) on MTX-induced liver damage. This study aimed at evaluating the effects of FA on protection against liver damage induced by MTX in mice.

MATERIALS AND

METHODS

In this the mice were divided into five groups in a random manner: I) control; II) MTX (20 mg/kg); III and IV) FA (50 and 100 mg/kg) + MTX; and V) FA (100 mg/kg), and we measured serum factors, oxidative stress and inflammatory factors.

RESULTS

In the MTX group, accumulation of inflammatory cells, accumulation of red blood cell (RBC), and nuclear pyknosis (NP) were detected in the liver. In line with the histological data, the levels of nitric oxide (NO), malondialdehyde (MDA), interleukin-6 (IL-6), and tumor necrosis factor-α increased (TNF-α), whereas the reduced glutathione (GSH), catalase (CAT), total antioxidant capacity (TAC), superoxide dismutase (SOD), and glutathione peroxidase (GPx) content reduced in the MTX group. However, FA ameliorated these hazardous effects in the antioxidant and anti-inflammatory systems in MTX-treated groups.

CONCLUSION

Based on our findings, oxidative stress impairment and MTX-induced liver damage were ameliorated following FA pretreatment at both histological and biochemical levels. Therefore, FA can be effectively used in abrogation of MTX-induced toxicity.
